Language: Knowledge of Language and Vocabulary Acquisition
What this domain tests
This domain covers how language varies by context and how to build and apply vocabulary. Questions may ask you to choose the right register, interpret figurative language, or use context clues and word parts to define an unfamiliar word.
Concepts to master
- Register and formality: formal writing avoids slang and contractions; informal writing may use them. Match the register to audience and purpose.
- Precision and shades of meaning: choose the word that fits exactly - "reluctant" vs. "refuses," "glance" vs. "stare."
- Context clues: definition (often set off by dashes or "that is"), example, contrast ("unlike"), and inference from surrounding sentences.
- Word parts: prefixes (pre-, anti-, mis-), roots (aud = hear, dict = say, spec = see), and suffixes (-tion, -ous, -ify) reveal meaning.
- Figurative language: simile, metaphor, personification, idiom. Interpret the intended meaning, not the literal words.
Traps to expect
- Literal reading of figurative language - treating "a sea of faces" as water.
- Near-miss synonyms - a choice with the right general meaning but the wrong intensity or connotation.
- Register mismatch - slang in a formal letter, or stiff jargon in a friendly note.
- One clue overgeneralized - building a definition from a single prefix while ignoring context.
Rule of thumb
For unknown words, use a two-pass method: first read the whole sentence for overall meaning, then break the word into parts. Confirm your guess by substituting it back into the sentence and checking that the logic still holds.
Worked example
"The witness's account was incredible - no one could believe such a detailed story." The context ("no one could believe") shows the meaning is "hard to believe," not "excellent." Breaking the word into in- (not) + cred (believe) + -ible (able) confirms it. Substituting "unbelievable" keeps the sentence's logic intact.
